How an ECU Remap works

remapping of a vehicle

How do ECU remaps for petrol, TDi, GTi and HDi engines work?

Engine chipping (also known as remapping, mapping, ECU chip etc)  came about after the introduction of the ECU. Since the early 1990s, most engines have been controlled by an on-board computer, the engine control unit (ECU), which amongst other functions, defines the ignition timing, fuelling and boost pressure for all given engine speeds and loads. ECU remapping lets us change the way the engine is controlled – and engine tuning gives you a more engaging drive.

Our remaps offer a unique ECU remap for each car, Diesel engine tuning is different from a Petrol remap. A turbo diesel remap for one car will be different from another and petrol engine ECU remaps will be different again.  We arrive at the optimised settings for your make and model of vehicle, ensuring that each remap is as individual as the software inside your ECU, safely eliminating those ‘performance compromises’.  Learn more about the benefits of a remap here.

In most cases this remapped program is installed electronically and remotely through the car’s diagnostic port, there’s no replacement chip, and we don’t touch the ECU itself.

And we always test your vehicle before handing it back for you to enjoy, just making sure everything is operating as it should be.
